Hello I need help on it ​
Gnoma [55]
It would be 78/4=19.5 which would mean that he would be able to set 19 tables. To be able to set all of the tables he would need 2 more napkins because 19*4=76. 78-76=2 so they would need 2 more to finish the last table.

Answer:

Dan's car depreciated by 54% after 6 years.

Step-by-step explanation:

Price of a depreciating asset:

The price of a depreciating asset after t years is given by:

P(t) = P(0)(1-r)^{t}

In which P(0) is the initial price and r is the decrease rate, as a decimal.

Dan's car depreciates at a rate of 12% per year.

This means that r = 0.12, so

P(t) = P(0)(1-r)^{t}

P(t) = P(0)(1-0.12)^{t}

P(t) = P(0)(0.88)^{t}

By what percentage has Dan's car depreciated after 6 years?

Relative to the initial value, the value after 6 years is given by:

P(6) = P(0)(0.88)^6 = 0.46P(0)

The value after 6 years if 0.44 of the initial value, that is, there was a depreciation of 100 - 46 = 54%.

Dan's car depreciated by 54% after 6 years.
